LS04 RF Capacitance Level Switch

Brand: Intempco Controls, Inc.

The Intempco LS04 level switch is a highly reliable sensor which can detect the presence of solids, liquids, as well as liquid-liquid and solid-liquid interfaces.

It has both N/O and N/C contacts for high and low level indication.

The LS04 has a stainless steel probe with either Teflon or UHMW insulation, and has its solid state circuitry housed in a cast aluminum, moisture sealed explosion-proof NEMA 4X head.

The LS04 holds calibration over a wide range of temperatures, making it ideal for outdoor as well as plant use.
